Benefits of technology

The cable backplane system in this patent text describes a way to connect cables to a backplane with a cavity that holds the cables. The system includes a tray and cable connectors that have cables routed inside the tray. The tray has a front edge with an EMR (electromagnetic radiation) absorber that helps prevent the propagation of electromagnetic radiation into or out of the tray. This makes it easier to connect cables to the backplane without risking interference from electromagnetic radiation. The technical effect of this system is better protection and reliability for cable connections in high-density cable backbone networks.

Problems solved by technology

As the density of the systems increase and as the requirements for high speed lines become more complex, achieving a baseline level of signal integrity can be challenging.
Electrical connector systems that operate with data transmission rates above 10 Gbps (Gigabits / second) are often vulnerable to electromagnetic interference (EMI).
However, in order to perform maintenance on an individual tray, all of the trays in the chassis have to be powered down.

Embodiment Construction

[0015]FIG. 1 is a front perspective view of a cable backplane system 100 formed in accordance with an exemplary embodiment. FIG. 2 is a rear perspective view of the cable backplane system 100. The cable backplane system 100 is used in a data communication application, such as a network switch. The cable backplane system 100 interconnects line cards 102 and switch cards 104 using cable connector assemblies 106. The cable backplane system 100 may be used to interconnect with other types of connectors and / or cards, such as daughtercards, in other embodiments.

[0016]The cable connector assemblies 106 include cable connectors 116 that are interconnected by cables within the cable backplane system 100. The cable connector assemblies 106 eliminate interconnections via traces of a circuit board, such as a backplane circuit board. The cable connector assemblies 106 have improved signal performance along the signal paths between various connectors of the cable backplane system 100 as compared ...

Abstract

A cable backplane system includes a tray having a frame with side walls surrounding a raceway. The side walls extend to a front edge of the frame. The tray includes spacers coupled to the tray located proximate to the front edge. Cable connectors are held by corresponding spacers in position relative to the backplane. The cable backplane system includes an electromagnetic radiation (EMR) absorber extending along an opening in the tray to suppress the propagation of EMR into or out of the tray.

Description

BACKGROUND[0001]The subject matter herein relates generally to communication systems that utilize cable connectors.[0002]Communication systems, such as network systems, servers, data centers, and the like, use large printed circuit boards, known as backplanes, to interconnect midplanes, daughtercards, line cards and / or switch cards. The communication systems use high speed differential connectors mounted to the backplane and high speed differential connectors mounted to the line cards and switch cards to transmit signals therebetween. The backplane interconnects the various connectors using traces along the circuit board.[0003]As the density of the systems increase and as the requirements for high speed lines become more complex, achieving a baseline level of signal integrity can be challenging. At least some systems have replaced the traditional backplanes with cabled backplane systems. In cabled backplane systems, cable connectors of a tray directly engage mating connectors of lin...
